4 Claims. (01. 101-416) This invention ink that in using colored sand commonly known as smalts when sized that the best results were obtained and preferably the correct sizing encompassed 170 mesh.

It has also been found that when using a substance graded through a finer mesh size that when the same is applied to a display card that card printed in two colors.

Fig. 2 is a perspective view of a card showing the drying substance placed over the figures of one color.

Fig. 3 is a similar view after the loose drying substance has been removed from the card.

ranges from 125 to.

Fig. 4 is an enlarged section taken on line 4 4 of Fig. 3.

Fig. 5 is a perspective View of a display card holder commonly used. a

Referring to the drawing, may have the numerals 2 suitable hand operated printing machine of the type heretofore referred to. The numerals 47 are here shown as being printed with red ink while the cents mark 3 is shown as being printed with blue ink.

the card is viewed from coarser than 125 larger portion of the granule the outer face of the ink 2 so that the granules will be easily shaken therefrom or when brought in contact with one of the bars 5 of the display card holder 6 will be easily scraped from their place and will not only tend to smear but will leave spaces on the inked card which are not covered by the drying substance. ther noted that if too coarse a drying substance is used that the same will fill in the letters of smaller type so that the card is not readily legand it will be seen that the ible.

When the drying substance is used which has been ground and sized through a mesh finer than 170 mesh that the substance left a smudge or smear on the card where it contacted therewith outside of the printed surface and was therefore not acceptable to the user. It was only through a great deal of experimentation that a correct drying substance of the correct size was obtained and it was found that by using a ground and sized crystalline or granular substance passed through a mesh of 125 to 1'70 that suitable results were obtained but that the best results were obtained by using a substance that was passed through a mesh of 140.to 150.

I am well aware that colored sand or smalts has been used on inked show cards but this was for decorative purposes only and had the drawbacks as heretofore stated as no attempt was made to correctly size the same to accomplish results attained by applicant. I am also aware that years ago sand was sprinkled on inked surfaces to dry the same but did not adhere to the inked surface but was shaken therefrom but this method did not accomplish the results attained by applicant.

It will be understood that the word show card applies not only to cards but to posters or papers or the like.

From the foregoing description it becomes evident that I have provided a method of treating inked show cards prior to the drying of the ink whereby the ink is immediately dried and a card is obtained in which the drying substance remains on the inked surface and is of a flat nature projects beyond It will be furso that the card does not reflect the light when viewed at an angle and further that the drying substance is of such character as to not smear or smudge the card outside of the inked surface when applied thereto and will remain on the printed surface and will not fill in the small letters thereby providing a card which is readily legible.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is- 1. The method of preparing a printed show card prior to the drying of the ink thereon, which consists of applying a ground crystalline substance, sized through a mesh of 125 to 1'70, to the printed surface of the card whereby the granules of the substance are sufficiently small to closely adhere to the inked surface.

2. The method of preparing a printed show card prior to the drying of the ink thereon, which consists of applying a ground granular substance, sized through a mesh of 140 to 150, to the printed surface of the card whereby the granules of the substance are sufficiently small to closely adhere to the inked surface and sufficiently large to prevent smuding of the surface of the card not covered by the printed matter thereon.

3. The method of preparing a printed show card prior to the drying of the ink thereon, which consists of applying a ground crystalline substance, sized through a mesh of 140 to 150, to the printed surface of the card whereby the granules of the substance are sufficiently small to closely adhere to the inked surface and sufficiently large to prevent smudging of the surface of the card not covered by the printed matter thereon. r

4. The method of preparing a printed show card prior to the drying of the ink thereon, which consists of applying a ground granular substance sized through a mesh of 125 to 1'70 to the square inch to the printed surface of the card whereby the granules of the substance are sufficiently small to closely adhere to the inked surface.
